You would like to have a safety knife with a large blade extension? Or are you looking for a worthy replacement for either OPTISAFE or MAXISAFE? In both cases, the SECUPRO MEGASAFE is your top choice. Thanks to a cutting depth of up to 20 mm, this cutter doesn't shy away from a challenge. And no matter your task, safety is always guaranteed; the fully automatic blade retraction functions even when you decide to not fully extend the blade.
